The Types of Non-Hodgkin's Lymphoma
Lymphomas are cancers of the lymph system which ironically is part of the body's defense mechanism to fight off infections and diseases. But sometimes the abnormal growth of the healthy lymphatic cells causes the tissues to mass up creating tumors and eventually becoming cancer cells. If left untreated, the cancer cells can easily break away from the tissues and begin infecting other parts of the lymphatic system and eventually moving to other organs of the body. There are essentially two kinds of lymphomas, the Hodgkin's lymphoma and non-Hodgkin's lymphoma.
Hodgkin's lymphoma is characterized by the presence of Reed-Sternberg cells. Other lymphomas do not contain these cells so the rest of the lymphomas were classified as non-Hodgkin's lymphoma or NHL. There are a number of sub-types of non-Hodgkin's lymphoma. Each are quite distinct targeting specific age groups aside from having unique forms.
One kind of NHL is the lymphoblastic lymphoma or LBL which commonly occurs in children. In fact about 30% of documented cases of lymphomas in children have been classified as lymphoblastic lymphomas. LBL is very aggressive kind of NHL and has caused quite a number of deaths in the past. But because of modern medicine and treatment techniques, LBL patients have better odds of surviving the ordeal.
Unlike LBL, the diffuse histiocytic lymphoma type or DHL is a slow growing cancer. And because it is slow-growing the cancer is quite hard to detect. Also, there are times where the cancer reappears after treatment.
Another kind of NHL appears closer to the body's surface. The cutaneous T-cell lymphoma or CTLC is a kind of lymphoma that affects the skin. What happens is that the white blood cells of the skin become cancerous. At first, the signs are dry, scaly skin with red or dark patches. These areas of the skin also itch a lot. But as the cancer cells continue to grow, the skin will develop highly noticeable tumors. Eventually the cancer cells enter the blood stream and spreads all over the body which soon infects other tissues and organs.
Although not common, the mantle cell lymphoma is another kind of non-Hodgkin's lymphoma. This cancer borders on being rare since only an estimated 5% of people diagnosed with NHL have it. It seems that the cancer is more likely to occur in men 50 years old and older. The cancer starts off as a slow growing lymphoma but can suddenly become aggressive in later stages.
Doctors have made 4 classifications or stages of non-Hodgkin's lymphoma which basically indicates how fast and how far the cancer cells have spread. Stage 1 is when the cancer cells are grouped in lymph node or organ of the body. In stage 2 the cancer has spread to two or more groups of lymph nodes or organs on the same side of your diaphragm. Stage 3 is where the cancer cells have infected organs on both sides of the diaphragm and finally stage 4 is when the different types of non-Hodgkin's lymphoma have gone beyond the lymphatic system and infecting other organs like the liver, bones, and lungs.
